发明名称 Method for making a seamless apertured metal belt
摘要 The present invention provides a method for making a seamless apertured belt comprising the steps of: (a) providing a strip of material having two opposing ends and having a length at least equal to a finished belt length; (b) providing an aperture pattern having a length substantially equal to the finished belt length, the pattern including a plurality of two-dimensional geometrical shapes, the pattern having opposing end edges which can be tiled together; (c) removing a pre-determined portion of each end of the pattern and joining the pre-determined portions to one another along the opposing end edges to form a re-etch pattern; (d) forming apertures in the strip corresponding to the two-dimensional geometrical shapes in the pattern, the strip remaining free of apertures in regions near each end comprising fusion zones; (e) fusing the ends of the strip to one another such that the fusion zones form a common fusion zone; and (f) forming apertures in the common fusion zone corresponding to the re-etch pattern. In a preferred embodiment, the two-dimensional pattern is an amorphous two-dimensional pattern of interlocking two-dimensional geometrical shapes. The strip of material may comprise a material selected from the group consisting of metal, plastic, fabric, rubber, and combinations thereof.
